Aitziber

Abstract

Water soluble 2D crystalline monolayers of fullerenes grow on planar assemblies of engineered consensus tetratricopeptide repeat proteins. Designed fullerene-coordinating tyrosine clamps on the protein introduce specific fullerene binding sites, which facilitate fullerene nucleation. Through reciprocal interactions between the components, the hybrid material assembles into two-dimensional 2 nm thick structures with crystalline order, that conduct photo-generated charges. Thus, the protein-fullerene hybrid material is a demonstration of the developments toward functional materials with protein-based precision control of functional elements.

Abstract

The synthesis of a new series of electron donor-acceptor conjugates in which the electron acceptor-[C.sub.60]-and the electron donor-[pi]-extended tetrathiafulvalene (exTTF)-are bridged by using m-phenyleneethynylene spacers of variable length is described. AFM spectroscopy is used for showing the ability of these new conjugates to form wirelike structures upon deposition onto a mica surface.

Abstract

Two new tetrafullerene nanoconjugates consisting of four [C.sub.60] units that are covalently connected through different [pi]-conjugated oligomers (oligo(p-phenylene ethynylene) and oligo(p-phenylene vinylene)) were prepared. Both the nanoconjugates exhibited a very fast deactivation of the singlet excited state of the core unit that produces a mixture of a charge-separated state, involving a radical cation on the [pi]-conjugated oligomer and the fullerene anion at one of the termini.

23. Supramolecular Electronic Interactions in Porphyrin–SWCNT Hybrids through Amidinium–Carboxylate Connectivity

Author

Rodríguez-Pérez, Laura, Vela, Sonia, Atienza, Carmen, and Martín, Nazario

Abstract

New supramolecular (metal)porphyrin/SWCNT hybrids have been synthesized through a combination of hydrogen bond and electrostatic interactions. Our experimental findings reveal through different techniques (XPS, TGA, UV−vis, Raman, and TEM) an efficient n-doping of the SWCNT from the electron donor (metal)porphyrin through the efficient and strong amidinium–carboxylate connectivity.

27. Supramolecular One-Dimensional n/p-Nanofibers

Abstract

Currently, there is a broad interest in the control over creating ordered electroactive nanostructures, in which electron donors and acceptors are organized at similar length scales. In this article, a simple and efficient procedure is reported en-route towards the construction of 1D arrays of crystalline pristine C60 and phenyl-C61-butyric acid methyl ester (PCBM) coated onto supramolecular fibers based on exTTFpentapeptides. The resulting n/p-nanohybrids have been fully characterized by a variety of spectroscopic (FTIR, UV-Vis, circular dichroism, Raman and transient absorption), microscopic (AFM, TEM, and SEM), and powder diffraction (X-ray) techniques. Our experimental findings document the tendency of electroactive exTTF-fibers to induce the crystallization of C60 and PCBM, on one hand, and to afford 1D n/p-nanohybrids, on the other hand. Furthermore, photogenerated radical ion pairs, formed upon visible light irradiation of the n/p-nanohybrids, feature lifetimes on the range of 0.9-1.2 ns., Unión Europea.

Abstract

Abstract: The development of sophisticated ordered functional materials is one of the important challenges in current science. One of the keys to enhance the properties of these materials is the control of the organization and morphology at different scales. This work presents a novel bioinspired methodology to achieve highly ordered donor/acceptor bio‐nanohybrids using a designed repeat protein as scaffold, endowed with photoactive and electron donating porphyrin (P) units, to efficiently wrap around electron accepting single wall carbon nanotubes (SWCNT). A systematic experimental and theoretical study to evaluate the effect of the length of the protein reveals that longer proteins wrap around the SWCNT in a more efficient manner due to the stronger supramolecular interaction existing between the inner concave surface of the protein (namely Trp and His residues) and the convex surface of the (7,6)‐SWCNT. Interestingly, spectroscopy and X‐ray diffraction data further confirm that the so‐called protein‐P–SWCNT donor–acceptor bio‐nanohybrids retain the original protein structure. Finally, the new bio‐nanohybrids show a remarkable enhancement on the photoconductivity values by flash‐photolysis microwave conductivity (FP‐TRMC technique) demonstrating that the major charge carriers of electrons are injected into the SWCNTs and move along the 1D‐structures.

41. ¿La poesía lírica es mimética y filosófica? Poesía y filosofía en la Poética.

Author

Trueba Atienza, Carmen and Trueba Atienza, Carmen

Abstract

En su tratado de la Poética, Aristóteles utiliza las palabras filosófico y universal en un sentido lato y esto dificulta entender lo que significa que la poesía sea “filosófica”. El propósito de este artículo es explorar una línea hermenéutica del dictum aristotélico “la poesía es filosófica” que parte de la pregunta en torno al estatus mimético, universal y filosófico de la poesía lírica, a la luz de la teoría mimética de la poesía esbozada en la Poética. El análisis de lo universal en la poesía lírica es utilizado en este trabajo para interpretar la idea aristotélica de la relación entre la poesía y la filosofía, en un sentido próximo al de los partidarios de la interpretación cognitivista extrema. No obstante las objeciones a la posición cognitivista representan una base sólida para cuestionar la conclusión cognitivista extrema y concederle un sentido más moderado a la tesis aristotélica del parentesco entre filosofía y poesía., In the Poetics, Aristotle uses the words philosophical and universal in a wide sense with regard to poetry; this makes it hard to understand what it means for poetry to be “philosophical”. The aim of this paper is to explore an interpretation of the Aristotelian dictum: “Poetry is philosophical”, beginning with the question concerning the mimetic, universal, and philosophical status of lyric poetry, in light of the mimetic theory of poetry sketched in the Poetics. An analysis of the universal in lyric poetry is used to interpret Aristotle’s idea of the relation between poetry and philosophy, in a sense akin to the extreme cognitivist interpretation. Nonetheless, objections to the cognitivist interpretation give us a good basis to question the extreme cognitivist conclusions and to grant a more moderate sense to the Aristotelian thesis of the relation between philosophy and poetry.

45. La naturaleza de los principios de la acción y el problema de la fundamentación de la ética en Aristóteles.

Author

Trueba Atienza, Carmen and Trueba Atienza, Carmen

Abstract

The principles of action (tas praktikas arjas) are a key piece of theory Aristotelian theory of action and an essential element for understanding the notion of rationality practice of Aristotle and its differences with Plato's ethical fundamentalism. The purpose of this paper ** is to clarify the nature and role of the principles of good in practical reasoning (ie, reasoning leading to action), and doing see some of its implications for Aristotle's own notion of practical science. Aristotle distinguishes two classes of propositions on the good and the just thing: one, that corresponds to the general definitions of good and fair that are valid for "most of the cases "(hos epi to polú) and another concerning what he himself understands as the proper property of human nature (i.e., its ergon or proper function). My examination of this question is centered, especially, on the first type of definitions (i.e., hospi to polú) and s its role in the practical reasoning., Los principios de la acción (tas praktikas arjas)son una pieza clave de la teoría aristotélica de la acción y un elemento imprescindible para comprender la noción de racionalidad práctica de Aristóteles y sus diferencias con el fundamentismo ético de Platón. El propósito de este trabajo** es aclarar la naturaleza y el papel de los principios de lo bueno en el razonamiento práctico (i. e., el razonamiento que lleva a la acción), y hacer ver algunas de sus implicaciones para la propia noción aristotélica de la ciencia práctica. Aristóteles distingue dos clases de proposiciones sobre el bien y lo justo: una, que corresponde a las definiciones generales del bien y de lo justo que valen para “la mayoría de los casos” (hos epi to polú) y otra relativa a lo que él mismo entiende como el bien propio de la naturaleza humana (i. e., su ergon o función propia). Mi examen de esta cuestión está centrado, especialmente, en el primer tipo de definiciones (i. e., las proposiciones hos epi to polú)y s su papel en el razonamiento práctico.
